This happens all the time, I have a collection of WWE games that were made in the original Smackdown era in the early 2000's (2000 - 2003) or Smackdown vs RAW since 2004 until 2011 (although the last one I had was 2010). Occasionally I'll boot up my PlayStation 2 for old times sake and when I'm playing an Exhibition match against the CPU, I forget how to counter a strike or a grapple because I'm so used to pressing R2 to block in the 2K series or punch or grab using X or Circle instead of Square to punch and X to grab them. It's even worse when you go back to the early Smackdown games until Here Comes The Pain when you couldn't escape a submission hold, you had to hope that your opponent let go or you automatically tapped out (which they fixed in the recent games). The wrestlers got back up faster even when you did a finishing move and it was easier to win or lose, which makes you appreciate the new games that fixed most of these issues.
